They say that the best way to justify expensive clothes is to assess them on a 'Cost per Outing' basis by dividing the expense by the number of times worn.
Your MOG must surely be a lower cost per outing/mile than the average Outfit or Handbag measured over the piece, so just keep it T&I'd and then use it as often and for as long as you can.
